so im curious, fellow seekers of info
would you first choose the lens you use and only then find the doctor who works with those brands/types ?
or would you choose the doctor and go with his lens choices (since no doctor would use all of them) or try to get him/her to use the ones you have chosen?
would a doctor even consider your choice of lens? would successful surgery be compromised by the doctor using an unfamiliar lens?
thanx. all important things to consider
Either way. If you can research and come to a tentative conclusion, I would start with lens. If you want a pretty standard lens, then start with the doctor. In particular, the light adjustable lens has fewer doctors that do it.
Lens makers will have find a doctor, locate a surgeon, or similar on their websites. If you don't see a link for that, use the search function for find a doctor etc.
I would choose one or more lenses that you prefer first, and then find a surgeon that also uses and prefers that same lens. You do not want to force a surgeon to use a lens that they have no experience with. Many clinics only use one brand of lenses so if you go to that clinic for advice, guess what they will recommend?
Doctor first. Someone who comes recommended, not from internet ratings, but people you know, preferably at a highly rated eye hospital. Your lens choice means nothing if the surgeon is sub-par.
Yes Bookwoman!
So, Dapper what are your plans for your eyes!
Sorry, but I can't agree. A poor lens put in by a good doctor is still a poor lens. Unfortunately the reality today in most clinics that do cataract surgery is that they are tied to one manufacturer of lenses. When you have picked the surgeon, you have essentially picked the lens. But yes for sure you want a good surgeon. However there are good surgeons doing most of the more common lenses.
IRon I think the main monofocal iols are all pretty good. J&J , Alcon, B&L.
Yes, good, but there are differences especially in asphericity. The Tecnis 1 targets zero net asphericity and potentially gives the best visual acuity but the poorest depth of focus. The B+L enVista has the most residual asphericity and compromises visual acuity some, but gives the most depth of focus. The Clareon falls in between. So, I guess it depends on one's knowledge of what the lenses offer and priorities. . There is also the issue of having blue light filtering or not.
I would add that, as I have said before, you want a skilled surgeon, but also one who will listen to you, work with you, and one you feel comfortable with. I know of some skilled, experienced cataract surgeons who use the Tecnis 1, but they won't try telling patients about refractive target outcomes. They will just aim for distance and use glasses to correct for near vision.
Yes, those are all important factors to consider too.
at this point i am clueless (really not clueless but indecisive)i have been experimenting with mini monivision with a -1.25 difference. i dont love it but i could get used to it. i also have to remind myself that i am doing this test with cataracts so the experience is skewed ie: everything would be much better after surgery.
still gathering info. i am in the -5.50 to -6 range of myopia so i am used to glasses. my goal is to NOT be unable to function at night when driving or any outdoor activity. i hate limitations and this one is very annoying. i also do not want to be putting on and taking off glasses constantly. i know ones personality will affect the choices one makes so i have to take that into consideration.
ron, please explain "asphericity again please
and what is the issue w blue light filtering?
Asphericity: This is a measure of the sharpness of the focus of light from all parts of the lens. Zero net asphericity is when all light from the edge of the lens to the center is brought to the same focus point. The Tecnis 1 lens theoretically has zero asphericity. It can provide the sharpest focus at distance (if set for distance) but will not have the depth of focus at closer distances. A lens like a B+L enVista has +0.27 um of asphericity in the average eye. The sharpness of the focus is a little reduced, but the depth of focus is increased allowing one to see a little closer with a lens set for distance. The Alcon lenses are somewhere between these two for asphericity. . Blue Light Filtering: The young natural eye has blue light filtering. Most Alcon lenses have blue light filtering to match the colour balance of a young natural eye. Most J&J lenses have no blue light filtering and yield a more blueish colour balance. However more recently J&J have been offering some models called OptiBlue that have some blue-violet light filtering. The advantage of blue light filtering is a more natural colour balance, and to some degree possibly higher contrast sensitivity in dimmer light conditions. The filtering takes out some of the chromatic aberrations in the lens. . I will post a grahic on the asphericity issue in a separate post. It will get delayed in moderation, so check back tomorrow...
Here is a graphic from B+L that shows the tradeoff of asphericity vs visual acuity of the common lenses. I added the red dot as to where I think the J&J Eyhance lands on the curve. The Clareon lens would land in the same spot as the AcrySof lens on the graph.

My experience was that to get the same near vision as my natural eyes simulating -1.25 D with a contact, I had to get -1.50 D with an IOL. The natural eye, even when we get older still has some accommodation ability.
I see. Well, be sure to find a cataract surgeon, like I said, who will WORK with you and not TELL you what to do. That may take some shopping around. Mini-monovision does work well for most people, but not all people. If you think you may have issues with that, then don't do it. You can always wear glasses. Now, the Clareon monofocal is said to provide good intermediate and near vision and excellent distant vision. If you get on the Alcon.com website you can locate a cataract surgeon who uses Alcon lenses near you. The Johnson and Johnson Eyhance, which is not a pure monofocal, but for insurance purposes is a monofocal, is also said to provide good intermediate/near vision and excellent distant vision, although that has been disputed. Nevertheless, it is in wide use among surgeons who use the Johnson and Johnson line of lenses.
How dense are your cataracts? I kept delaying my surgery and mine became +4, very dense. Don't let yours get that dense. Also, I would't stay too indecisive and develop "analysis paralysis" like some posters have done here. Remember, millions of people have had cataract surgery and most are satisfied with the outcome. You'll be all right.
Well, DapperDan, I wouldn't stress over your decision too much and get " analysis paralysis" like some posters here have done. It's easy to get lost in the weeds. Millions of people have cataract surgery every year and most are satisfied. If you aren't sure about mini- monovision, don't do it. Just find a surgeon who will work with you. That may take some shopping around. Don't delay too long and get +4 very dense cataracts like I did. I used the J&J Tecnis I set for intermediate vision and I was satisfied. Some here have liked the J&J Eyhance. Maybe the best of all is the Clareon, which is said to give good intermediate and near vision and excellent distant vision. That's what the Eyhance also claims to do, but some doubt that. Just do it, as they, You will be all right.
I thought the Clareon monofocal provided good vision at one focal point. Near, intermediate or distance, all depending on the Target that you choose. I think I understand that the lens is a monofocal and slightly aspheric but does it really give that large of a range of focus that has image quality?
